"Transportation officials in Texas are scrambling to prevent hackers from changing messages on digital road signs after one sign in Austin was altered to read, "Zombies Ahead."
Chris Lippincott, director of media relations for the Texas Department of Transportation, confirmed that a portable traffic sign at Lamar Boulevard and West 15th Street, near the University of Texas at Austin, was hacked into during the early hours of Jan. 19.
"It was clever, kind of cute, but not what it was intended for," said Lippincott, who saw the sign during his morning commute. "Those signs are deployed for a reason — to improve traffic conditions, let folks know there's a road closure."
